Fuel economy figures for the 2021 Ford Bronco have been released before customer deliveries of the popular off-roader begin.

Unsurprisingly, the entry-level 2.3-liter EcoBoost four-cylinder is the most fuel-efficient of the two available engines and in Base, Big Bend, and Outer Banks configurations, is rated at 20 mpg city, 22 mpg highway, and 21 mpg combined. These figures are identical regardless of whether the Bronco has the seven-speed manual or the 10-speed automatic transmission.

The Bronco 2.3-liter in Badlands guise with the auto ‘box returns 18/17/17 mpg while the Black Diamond is rated at 18/18/18 mpg. A 2.3-liter Bronco with the Sasquatch package and automatic is also rated at 18/18/18 mpg, and manual variants of the 2.3-liter Black Diamond and Badlands are rated at 17/19/18 and 16/18/17 mpg respectively.

As for the 2.7-liter EcoBoost V6 offered exclusively with the 10-speed automatic, it returns 18/20/19 mpg in base form, Big Bend, and Outer Banks guise, while the 2.7-liter Badlands returns 17/18/19 mpg and the 2.7-liter Bronco with the Sasquatch package is rated at 17/17/17 mpg.

“With off-road competition-proven EcoBoost engines and class-exclusive transmission offerings, our all-new Bronco two-door and four-door models deliver the best four-cylinder horsepower and torque, and the best available six-cylinder gasoline horsepower and torque in its class,” a Ford spokesperson said of the EPA-estimated fuel economy ratings.

These ratings come just a few days after it was revealed that the 2.3-liter EcoBoost is rated at 300 hp and 325 lb-ft (440 Nm) with premium fuel while the 2.7-liter EcoBoost V6 is good for 330 hp and 415 lb-ft (562 Nm) on premium fuel.
